please post rwhp #'s on a revup vortech setup.
I am just curious on what rwhp numbers people are making on the REV-UP vortech kits weather it be a tuner kit or the full kit. i am convinced the 34/32 cog configuration is holding people back from making low to mid 4xxrwhp numbers on a dyno jet. i say this due to my own R&D, the most i could ever get out of the tuner kit was 380 rwhp. that was with a utech,550 injectors,255lph pump, cjm stage1 return fuel system,stillen headers,aps 2.5" duals, aps 2.5" test pipes and mrev lower with 5/16 spacer. once i swapped out to the 32/28 NON REVUP cog setup "still Sc-trim vortech" i was hitting 420 rwhp no problem with a very conservative tune. at this time Sam from GTM is designing a rock solid setup to convert the revup to a non revup cog configuration that will hold up to hard abuse. my car is currently being used as a test mule for this application/conversion with a Si trim vortech head unit.

oh and i forgot to add that the 380ish RWHP #'S are with a 2.87 serp pulley!
(that basically works out to a 3.12 serp on a non revup setup). some people talk about going to a 2.62 serp but that pulley would be a world of trouble in my opinion. can you say BELT SLIP!!!!!!!!!! i also dont think the 2.62 will clear due to the jack shaft bearing housing being to large. even if the 2.62 pulley had a considerable amount of material machined off the back side it still would not clear in my opinion. i had to machine about .010" off of the back side of the 2.87 pulley to get it to fit!

Here are our dyno's done at SGP with the mods listed in our sig. We did NOT change any of the cogs from the RevUp kit on the 3.12 pulley.
